Why won't my wall heater turn off? ›

There are a couple potential reasons why your heating system won't turn off: Bad thermostat: A faulty thermostat can normally be repaired. Faulty wiring, a broken switch, or broken heating sensor can be fixed depending on how severe the issue is.

It's a small electric heater (a lot of ours are about 9-by-12 inches on the front and about 4-inches deep) that is installed in your wall that is used to heat an individual room. They can be used as the only heat source in homes or to add a little warmth to a room in a home with a central heating system.

There are several reasons why your furnace may not turn on. The most common include a broken thermostat, gas line issues, clogged air filters, blocked ductwork, a tripped circuit breaker, and issues with the furnace itself.

A clogged air filter dramatically reduces the airflow throughout the heating system. As a result, the heater won't be able to circulate enough heat through your house. It will keep running in an attempt to maintain the set temperature. To avoid such issues, change the air filters after every three months.

Cut power to the unit, remove the thermostat knob, control knob and faceplate, then remove the unit from the wall to check all the wiring connections inside. Tighten any disconnected or loose connections. If this doesn't work, the unit may need a new heating element.

The cause of your furnace not blowing hot air could be the thermostat configuration, a dirty air filter, the high limit switch, a clogged condensate line, insufficient fuel, leaky ducts, ignition problems, a blocked burner, flame sensor issues, gas valve malfunctions, a cracked heat exchanger, or a clogged coil.

A faulty thermostat can cause your heating unit to run and not turn off. The unit may have a broken heating sensor, the wiring may have gone bad, or the switch itself may have broken. The older the thermostat is, the more at risk you are for this happening. Fortunately, a broken thermostat is an extremely easy fix.

If your home radiators will not switch off even when the central heating isn't on, the most likely cause of the issue is troubles with a diverter or check valve. Should the valves become damaged or blocked, they can continue to transport hot water to your radiators even when the thermostat is switched off.

Why is my heater turned off but still running? ›

One of the most common issues is the thermostat. The wiring, switches, or heating sensors can fail on your unit. If this is the case, then you'll need to replace the thermostat with a newer model. A damaged primary controller can also cause the furnace to stay turned on.

The persistence of a system that won't turn off can be attributed to a variety of factors. Encompassing faulty thermostats, scaled heat exchangers, oversized boilers, damaged zone valves, or defective pressure relief valves.
